A Ponzi scheme requires a central actor like Charles Ponzi, you're quoting a description of a "purely algorithmic stablecoin" which implies no central actor to channel new investors' money to old, no central actor to defraud the new investors and by telling them they've gained money when they haven't.
I guess they are comparable in the way that they both require a inflow of capital, is that what you're saying? That would make them similar to pyramid schemes and startups too. "Ponzi scheme" is more specific than "scheme."
